Jaguar’s new diesel XJ has managed to achieve 44 mpg in an extensive test in Britain, reports Motoring.co.za. The car traveled the length of the UK — 840 miles from John O’Groat’s to Land’s End — and then backtracked an additional 160 miles.

Too bad the US probably won’t get this car.

On second thought the whole car is not needed just the fuel system or the entire powerplant. Ford needs to outsource this engine. If they hooked it up to a engine assist hybrid electric motor it may get better milage and pee on everyone parade…dang if only they had a vision.

Screw hybrids…I am sick of hearing about them. Clean diesel and hydrogen technology for me, please.

Everyone was so impressed when the diesel Audi A8 got 800 miles out of one tank (~42mpg). Glad to see the Jaguar could improve on that significantly. Shows that while aluminum construction helped both cars, not having quattro helps more.

Diesel? It’s still fossil fuels. At least Hybrids use rechargeable, renewable energy cells. Instead of looking at non-renewable, dirty sources, they have to look only at developing renewable, clean energy sources.
Anyways, nice to see Jag getting a large car like an XJ getting 44 mpg…much better than Mercedes, and their insane horsepower race (6.3 liter V8’s and 6.0 liter bi-turbo V12’s).

Where do I sign up for one? That mileage is AWESOME for the size and weight of the car. Imagine if all the people who drove large luxury sedans drove these instead (at least the engines is my point), there would be a lot of happy people – both the owners and the greenies.
Too bad it wont hit our shores. Diesel is an awesome fuel, especially since it is cheaper and easier to refine than gasoline. Hybrids don’t do any good if they gas doesn’t make it here by the way. If you really care about fuelling up in a “green” way, you need to look towards biofuels.

Woot for Diesel!

And yes, I use it for work. And ‘wheeling.

Diesel is not green, but it’s certainly more efficient (although quite slower too). Biodiesel is far from ready to replace good ol’ diesel.
“Diesel? It’s still fossil fuels. At least Hybrids use rechargeable, renewable energy cells. Instead of looking at non-renewable, dirty sources, they have to look only at developing renewable, clean energy sources.”
Read that again for me. Hybrids, by definition, still use fossil fuels as well. It’s not like it’s all on a battery, or it wouldn’t be a hybrid anymore.
Never mind the energy cost of creating the car or maintaining it, or replacement of batteries after five years…

You know what I mean, half the car is powered by a renewable resource, and companies guarantee the hybrid part of the car for 10 years.

Not that I know, but is there noone else besides me who wonders about the cost to produce the batteries? I mean, from an economic & enviroment standpoint? Batteries use chemicals (the hybrid ones do, right?), so aren’t they a “hazard” of some sort? I just think too many people quickly look at hybrids as a solution, and don’t look at all of the aspects.
I drive a big truck, but need the space, hauling ability and versatility. A hybrid minicar/sedan would do me no good. I need the power for work. Diesel & Biofuels are the direction we need to go, no doubt about it.

Diesels rule. Sooner or later Americans will understand that their hybrids cannot provide torque and acceleration like diesels can. Most diesel engines out-perform gasoline engines of similar size. Not to mention they last forever (how many 1970’s S-Class Turbodiesels and Volvo Diesels are still on the road? Plenty.) And diesels still get almost as good mileage as hybrids.

Put two turbos on the gasoline car and the argument about power and performance disappears (modern diesels have high-pressure turbos to give them great performance). But point taken that deisels are very good and actually can deliver equal or better MPG than gasoline/electric hybrids.
There is no one answer. Not hybrid. Not diesel. Not gasoline. Depends on the use of the vehicle.

I understand that diesel is cheaper to produce/refine, but has anyone noticed that diesel cost more at the pump than 92 octane? At least around metropolitan areas. Either way Oil companies are in WIN/WIN situations.

too bad the people who really need a car with this kind of fuel milage cant afford a diesel… though autoweek managed to get almost 50 mpg out of a lowly jetta diesel… better than either hybrid they took along by like 7 mpg…

In which world do you live in? Mercedes was the pioneer brand in establishing a luxury-diesel range, for decades.
The Jaguar brand never had diesels because purists say sports car don’t run on diesel engines. However, with sales slacking, they really do need a diesel engine to compete here in Europe. Almost all new 7-series, Audi A8s and Mercedes S-classes bought in Europe are diesel.
Why buy petrol engines, when diesel is more efficient and economical?
